So apparently when you execute your query the result has at least one
column but that column isn't named "snumber". I'm sure there is a way
in Python to debug "row" and find out what names it does have. Or maybe
Python 3+
print(row)
Python 2.7
print row
execute the query in something like psql and observe e column name there.
That said, by default the name of columns whose values are derived by a
single function call should be the name of the function. So
"translate", not "snumber" - the latter being consumed by the function.
You can as use "as <alias>" to give it a different fixed name and refer
to that.
